'291' 2.02 heads
picked up a pair of '68 3917291 2.02 heads this past week for an L79 project. one(K 1 7) has pressed in studs, 1.125 spring seats, the other(K 21 7)has screw in studs, 1.250 seats. i'm assuming these are off different engines. can't find any info as far as pressed/screw in studs or spring seat diameters.
 any thoughts? thanks.

Re: '291' 2.02 heads
They were pressed in studs from the factory. Are they 2.02 heads or are they 1.94 heads with 2.02 valves in them? The combustion chamber is machined around the intake valve on factory 2.02 heads to unshroud the valve.
